1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundThe Internet is increasingly utilized by patients to acquire information about dietary and herbal supplements (DHSs). Previously published studies assessing the quality of websites providing consumer health information about DHSs have been found to contain inaccuracies and misinformation that may compromise patient safety.. The present study assessed the quality of online DHSs consumer health information for fatigue.

methodsSix unique search terms were searched on Google, each relating to fatigue and DHSs, across four countries. Across 480 websites identified, 48 were deemed eligible and were quality assessed using the DISCERN instrument, a standardized index of the quality of consumer health information.

resultsAcross 48 eligible websites, the mean summed score was 47.64 (SD = 10.38) and the mean overall rating was 3.06 (SD = 0.90). Commercial sites were the most numerous in quantity, but contained information of the poorest quality. In general, websites lacked discussion surrounding uncertainty of information, describing what would happen if no treatment was used, and how treatment choices affect overall quality of life.

conclusionPhysicians and other healthcare professionals should be aware of the high variability in the quality of online information regarding the use of DHSs for fatigue and facilitate open communication with patients to guide them towards reliable online sources.
